INDUSTRY

Rural Broadband Operators

BACKGROUND

The U.S. rural broadband plan was created by the FCC and is known as the Connect America Fund, or CAF.

  • Provides funding to communications providers for building infrastructure to support rural broadband deployments

  • Expands broadband services to areas where not available

CHALLENGE

Rural Broadband Operators face significant challenges reaching underserved rural areas with broadband internet service that is affordable, reliable, and easy to deploy.

SOLUTION

TV White Space (TVWS) includes recently allocated wireless spectrum that, due to its low frequency band, can offer long range broadband connections to rural subscribers.

SRC Design partnered with Telco Design Connect to develop a TVWS antenna/radio module that has excellent RF performance, is compact and visually appealing for rural business and residential applications, and has very low cost.

RESULTS

  • Analysis and testing proves that the Compact TVWS Antenna can support broadband service delivery over required rural coverage areas

  • Densely packaged, high capacity 2X2 MIMO is achieved by integrating two antennas onto a single panel PCB

  • Compact antenna is significantly smaller than traditional Log Periodic antennas of similar RF performance

  • Pleasing aesthetics achieved by concealing the antenna PCB under a low cost, high impact injection molded radome

  • Unit cost is highly competitive using the single layer PCB antenna and design simplification through part consolidation

  • Demanding outdoor reliability requirements are met using an IP67 seal, a rugged impact resistant enclosure, and robust interconnect design

  • Interactive collaboration using Solidworks and RF analysis tool HFSS is an effective and fast method optimizing a PCB-based TVWS antenna design
